Substitute Part Grouping Explanation

Substitution eligibility for the 3299X-1-100 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 Ohms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 25 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Physical dimensions: Rectangular - 0.395" x 0.240" Face (exact match required)
• Series: Trimpot® 3299 - Sealed (exact match required)

The identified substitute part maintains full electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 3299X-1-100LF is a direct electrical and mechanical equivalent to the 3299X-1-100. Both parts are manufactured by Bourns Inc. and share identical specifications across all critical parameters including resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting configuration, termination style, and physical dimensions.

The primary distinction between these parts is RoHS compliance status. The 3299X-1-100 is RoHS non-compliant, while the 3299X-1-100LF carries ROHS3 compliance certification. Both parts maintain identical REACH Affected status and share the same ECCN and HTSUS classifications.

Selection between these parts should be based on regulatory requirements applicable to the end application. Applications requiring RoHS3 compliance must use the 3299X-1-100LF variant. Applications without RoHS compliance mandates may use either part based on availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Are the 3299X-1-100 and 3299X-1-100LF electrically identical?

A: Yes. Both parts have identical electrical specifications: 10 Ohms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, and Cermet resistive material.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts share identical mechanical specifications including through-hole mounting, PC pin termination, and rectangular form factor (0.395" x 0.240" face). They occupy the same footprint and require identical PCB layout.

Q: What is the difference between the 3299X-1-100 and 3299X-1-100LF?

A: The primary difference is RoHS compliance. The 3299X-1-100LF is ROHS3 compliant, while the 3299X-1-100 is RoHS non-compliant. All other specifications are identical.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 3299X-1-100LF. For applications without RoHS mandates, either part is suitable based on availability.

Q: Are both parts currently in production?

A: Yes. Both the 3299X-1-100 and 3299X-1-100LF are active products with current inventory availability (964 and 1323 units respectively).

Q: Do these parts have the same packaging?

A: Yes. Both parts are supplied in tube packaging.
